IMPROVEMENT IN HEM P-BRAKES.

T0 aZZ whom it may concern:

Be it knownthat I, HARVEY GUILD, of Oincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement on the Power Hemp-Brake, by which the amount of beating may be made to correspond with the condition of the hemp.

It is well known to practical men that one of the greatest obstacles to the breaking of hemp is its very changeable nature. For instance, not only does one parcel require much more beating than another, but even the same parcel will break with four times the facility on a dry day to w at it will on a damp one. So rapid, indeed, are these transitions that one hour often suffices to completely change the character of the hemp. It is to meet this obstacle that this machine is so contrived as that the operator can either withdraw the hank after a few strokes of the heater or as many more as thought necessary. Another formidable obstacleis the dust arising from the operation. This is almost insufferable at times, and extremely prejudicial to the health of the operator. A current of air, as I propose, will entirely remove this obstacle; and I do hereby declare that the following isa full, clear, and exact description of the same,

reference being had to the annexed drawings, making a part of this Specification, in which Figure 1 is a longitudinal elevation of the machine, the near side being removed to afford a view of the interior. Fig. 2 is a plan of the same, the top being removed for the same object that the side is in the other view.

a, the heaters, are cast-iron disks, each having a projecting tooth or arm, I), chamfered to a somewhat rounded edge at C. These beaters are fixed on a shaft, (1, which shaft also carrIes cams e.

f are fingers or prongs of cast or wrought iron, being chamfered to a roundish edge like that of the heaters, and hooked or bent over after the manner shown. These prongs are attached to a shaft, 9. This shaft is connected, by means of arm h, connecting-rods z, and beams j, with the yokes k, inclosing the cams e, which are so formed as at every revolution of the beaters to raise the prongs and the position of either one of the wrists Z Z Z and the exact period at which the prongsdrop by the position of the cam, which regularly increases in radius for about two-thirds of the for the remainder, and then drops square to the point of starting. The cross timber or takes the jar of the falling prongs.

In order to avoid the dust which is so deleterious to the operative hemp-worker, I effect or produce a current of air through the ma chine. This may be accomplished in various ways as, for instance, by blowing-oylinders, bellows, air-pump, or by a revolving fan. The latter plan is here shown. .a is such a fan, which draws the air into the machine at the place where the hemp is broken, and with it the dust, and ejects it through the spout 0 outside the room or building. This fan may be worked from the beater-shaft in the manner shown, or in any other suitable way.

possible to the place where the hemp is broken, the casing p is extended around every part but where the hank passes.
